Title: Power interruption detector and detecting method
Inventor: SHIMOYANAGIDA SUSUMU
IPC: G06F1/28
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous operation due to noise while prolonging the backup time by an arrangement wherein a microcomputer decides whether an AC commercial power supply is interrupted or not by counting pulse voltages. SOLUTION: An AC power supply 1 supplies power to the power supply terminal 6 of a microcomputer 5 through a transformer 2, a diode 3 and a capacitor 4. A phototransistor 20b on the output side of a photocoupler 20 has collector connected with a pull-up resistor 23 which is connected with the power supply terminal 6 of the microcomputer 5 and the collector voltage is introduced to the power interruption detection terminal 7 of the microcomputer 5. Consequently, the photocoupler 20 produces a pulse output voltage synchronized with the AC commercial power supply voltage.  Since pulses synchronized with the AC commercial power supply are employed as an input for detecting power interruption and the microcomputer 5 decides whether power supply is interrupted or not by counting the number of continuous pulses, erroneous operation due to noise is suppressed while improving the accuracy of time required for deciding occurrence of power interruption.

Title: Laser scanning device
Inventor: SHIGEKUSA HISASHI
IPC: G02B26/10
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a laser scanning device which is capable of stably irradiating the inside of the range of an assigned scanning angle with a laser beam even if the friction of a supporting shaft with an oscillation mirror increases. SOLUTION: The laser scanning device 1 executes an actual speed detection processing S12 to detect an actual speed and whether a target speed and the actual speed coincide or not is decided (S14). When the actual speed and the target speed are decided not to coincide, the processing to correct the pulse width of a constant voltage pulse is next executed (S16). Even if the friction between the rod magnet and the supporting rod of the laser scanning device 1 increases, the oscillation 14 is oscillated by correcting the pulse width of the constant voltage pulse in such a manner that the target speed coincides with the actual speed and, therefore, if the same scanning angle is assigned by a selector switch 18, the reading of bar codes of the same sizes is always made possible.

Filed: 1995-06-27
Abstract: PURPOSE: To provide an ID authentication system disabling duplication of a key even in the case that a content of a communication between a first and a second entities is intercepted by a third party. CONSTITUTION: An ID code A common to a first and a second entities is shared between them. The second entity side multiplies the ID code A by a random number R1 and calculates a message on (= A○1 ) and sends it to the first entity side. The first entity side divides n1 the ID code A to calculate the random number R1 . Thus, the key is judged as a right one only when the message is divisible by the ID code A. Since there is little probability that a random number is coincidentally divisible by the ID code A, the rightness of the key can be authenticated in a high probability.
